I have a 1995 ford ranger 2.3L this problem just occurred the other day recently. But not as severe as today, I’ve noticed within the truck itself at certain times it obtains total power loss. And start to act like it’s misfiring, and it back fires too at certain points. I’m not sure exactly what this could be, but at some points when I try to give my vehicle acceleration it bogs down the motor completely, but the motor runs fine at idle. When it lost all power it stalled, but started up again just fine and I managed to drive it home with no issues what so ever. I checked my air filter and it was pretty dirty, but everyone I knows says that may not have an effect as to why it does this. The check engine light doesn’t appear to come on when this does happen, and I’ve been told that it won’t because of the year my truck was designed. But it does have an OBD reader port, I just don’t understand why the light would only come on because of other things and not simple stuff like misfire.

 

Any misfires need to be repeated several times for any year computer to set a misfire code

You do have OBD2 but in 1995 Ranger it was a little different, 1st year for it
Auto parts store should be able to get any pending codes

Pending or history codes are set but don't turn on the CEL unless they are repeated, otherwise CEL would be on ALL the time, lol
All engine systems have glitches that set a code, but unless it is repeated a few times computer will eventually clear it

Stalling out could be the fuel pump starting to go out or a dirty fuel filter, limiting flow
There is no fuel pump or fuel flow sensor

 

I’m not sure if it may be a fuel pump, but I’m thinking not mainly because the truck started up just fine after it stalled from the misfire and ran perfectly. I’m coming down to an intermittent misfire, but I’m gonna start dialing things down and knocking off the obvious. I have heard fuel pumps do that before though, a friend of mine went through all the trouble of replacing a lot of stuff. When it turned out that the fuel pump he ordered from a nearby parts store, became faulty.

 

Yes, the thing about intermittent issues is.............they are intermittent, lol, real pain in the butt to diagnose until there is a complete failure

And yes, "new" parts now-a-days just means NEVER TESTED, but "we will replace it if its bad", so we are now the Quality Control Department for most parts makers

Ford, like most vehicle makers, pay more for their parts, i.e. Motorcraft brand, the extra cost is Quality Control, usually 10-15% of the parts are randomly tested by a human being before being box and shipped

 

Hi ANG,
It almost seems to me that a) you got a load of bad gas, or, b) your fuel filter is clogged.
When you command that throttle to open, there isn't enough gas to supply the rpm's requested.
That would explain the lack of codes.
